Description of key information

Boiling point 246.1 °C at 1013 hPa (OECD 103)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
246.1 °C

Additional information

A measured boiling temperature of 246.1°C at 1013 hPa was determined for the substance using the dynamic method in accordance with OECD Test Guideline 103 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.


This is supported by boiling point values of 142 °C at 20 mmHg and 245.5°C at 1013 hPa which were obtained from handbooks which have been subject to peer review in which the original sources are traceable.

In a secondary source to which reliability could not be assigned, boiling point value of 259.7°C was reported for the substance.
